In Finnish mythology, Vetehinen (a merman) is often portrayed as a magical, powerful, handsome, bearded man with the tail of a fish. Vetehinen can be a soul of a drowned man, who lured other humans to drown. But not always it is described as evil. Sometimes humans prayed better fishing fortune from Vetehinen. He can cure illnesses, lift curses and brew potions, but he can also cause unintended harm by becoming too curious about human life.
